What do you know about polyurethane

The development history of polyurethane

German scientists developed polyurethane in the 1930s. They condensed liquid isocyanate and liquid polyether or glycol polyester to form a new material, named polyurethane. In the 1940s, the United States flourished in the chemical manufacturing industry, and in the 1950s, polyurethane flexible foam was synthesized. This was an important research in the chemical industry at that time and provided a solid technical foundation for the future development of the polyurethane industry.

Characteristics of polyurethane

Polyurethane (PU) is a polymer compound, divided into two types: polyester type and polyether type. Polyurethane has a thermoplastic linear structure, good stability, chemical resistance, resilience and mechanical properties, and good thermal insulation, sound insulation, shock resistance and anti-toxic properties, and our Polyurethane water spray nozzle for vibrating screen also has the above characteristics.

Polyurethane product application areas

Polyurethane is a high-quality, high-performance material. In addition to being widely used in furniture, construction, transportation and other industries, polyurethane can also be used in some precision instruments. For example, the polyurethane water spray nozzle for vibrating screens is a high-quality water spray nozzle that is made of polyurethane material and has excellent durability and weather resistance. It can maintain its performance and shape for a long time and provide accurate water spray effects.

Our Polyurethane side pressure plate used in vibrating screen

Our Polyurethane side pressure plate used in vibrating screen is made of polyurethane, which has good performance and can be sprayed evenly to avoid material accumulation and blockage and improve screening efficiency. Our Polyurethane water spray nozzle for vibrating screen is wear-resistant and stable for long-term use, absolutely ensuring the continuity of screening work.
